What Projects Can Be Done In AutoCAD?

Autodesk AutoCAD is a general purpose CAD software application. As such, it can be used for drafting and design projects that involve creation, editing, viewing or printing various types of geometric 2D and 3D entities. Basically, this includes various projects in areas of architectural, civil, mechanical or electrical engineering drawing and design.

Do Civil Engineers Need To Learn AutoCAD?

The general consensus among experts online is that civil engineers do need to know their way around CAD software.  According to many structural engineers, like Norbert Pozsonyi at Quora, AutoDesk’s AutoCAD is an essential CAD software tool to learn and know. Learning AutoCAD will at least help you to read drawings, which is of vital importance for civil engineers.

Whether and how much you will really need it in practice, depends on where you are (in which part of the world) and what software is used at the company you work for.

What CAD Software Does A Civil Engineer Need To Know To Land A Job?

Autodesk’s AutoCAD is an industry standard used by the vast majority of civil engineers and construction firms, but there are still many others that use different CAD software. So, if you have to pick one CAD software to learn, choose AutoCAD. But, to improve your prospects of landing a job as a civil engineer, you may want to learn a few other CAD software applications. Some of the most commonly used ones that will add extra strings to any civil engineer’s bow include MicroStation, Revit and Tekla.  A comprehensive list of CAD editors and a comparison of computer-aided design solutions is available at Wikipedia

What Is The Difference Between AutoCAD And AutoCAD 360?

AutoCAD is a commercial computer-aided design (CAD) desktop software application for 2D and 3D design and drafting. It’s used for creating blueprints and other engineering plans. AutoCAD is mostly used by drafters in architectural drafting, civil drafting, mechanical drafting, electrical drafting, electronics, aeronautical drafting, and beyond.  

AutoCAD is available for Microsoft Windows and Mac OS X.

AutoCAD 360, on the other hand, is a web and mobile drawing and drafting application that allows registered users to view, edit and share AutoCAD drawings via web and mobile devices. AutoCAD 360 is used by general contractors, project managers and tradesman with little to no experience with CAD and is commonly used across a wide range of industries: architecture, engineering and construction, mechanical, electrical, plumbing, and more.

AutoCAD 360 is available for download as a mobile app for Android and iOS devices.

What Is The Difference Between AutoCAD And Solidworks?

A CAD analyst Sandeep Kumar summed it up on Quora: Autodesk’s AutoCAD was initially designed for 2D drafting and subsequently extended with some 3D features. SolidWorks, on the other hand, is a full featured 3D modelling CAD software.

Solidworks Resource Homepage

When it comes to 3D modelling, SolidWorks is for the advanced users and tasks, while AutoCAD is mainly for intermediate 3D modelling.

However, while AutoCAD is available for both Microsoft Windows and Mac OS, Solidworks runs exclusively on Microsoft Windows OS.  

Autodesk’s Inventor is actually Solidworks’ counterpart, rather than the often compared AutoCAD

What Are The Differences Between AutoCAD, AutoCAD Architecture, 3DS Max And Revit?

AutoCAD is, as already mentioned above, primarily a 2D drafting software with moderate 3D modelling capabilities. It uses lines to graphically represent objects.

AutoCAD Architecture is a specialized version of AutoCAD with additional tools designed specifically for architects to enhance their workflow, aiding in tasks such as architectural planning and construction documentation.

Revit is a 4D BIM modeling software with tools for planning and tracking various stages in a building’s lifecycle, from concept to construction and eventual demolition. Simply said,  Revit is used for building computer models of physical structures. It allows users to create actual objects with attached parameters and data like material, as opposed to just creating lines that graphically represent objects. It should be noted that Revit is a building modelling tool, and isn’t used for generic modelling purposes.

Autodesk 3ds Max is a 3D modelling, animation and rendering software. It’s mostly used for making 3D animations, games, images, movie effects and movie-pre-visualization. Its most common users are video game developers, TV studios and architectural visualization studios. While AutoCAD is primarily used for drafting, 3ds Max is mostly used for presentation. These two are both are geometric modellers, while AutoCAD Architecture and Revit are classified as BIM modellers.

Despite the differences between them, these programs primarily handle design and its implementation into usable construction and presentation documents.

What Are The Limitations Of AutoCAD Supported .DXF File Format?

To identify limitations or advantages of the .DXF file format, it is necessary to compare it to AutoCAD’s native .DWG format.  What can these formats do and which should you use?

Although both file formats are developed by Autodesk and supported by AutoCAD, there are some differences between the two vector image file types. The main one is that DWG (which stands for DraWinG) files only work with Autodesk’s AutoCAD, while .DXF (meaning drawing exchange/interchange format) was developed to allow other CAD programs to open and use information from the drawing file.

Furthermore, some CAD programs can’t import .DWG files, but they can import .DXF. That being said, if you’re a CAD user who doesn’t use AutoCAD, the ability to open and use the .DXF file in other CAD programs is its obvious advantage over the DWG.     

Possible limitations of .DXF in comparison to DWG are:

  • DWG files retain all drawing layers, colors, lines weights and x-references, while DXF files retain lines, dimension and text only.
  • While DXF is ACSII text, DWG is a binary file. This means that .DXF is more bloated in size than DWG.  

Despite these potential drawbacks, the ability to work with all vector-based programs has made the .DXF the most pervasive vector file type in the CAD industry.

Is It Possible To Convert TIFF To AutoCAD File?

It isn’t possible to directly convert TIFF image to DWG/DXF, but there’s a workaround you can try if you need to reuse a TIFF image in AutoCAD. Use the IMAGEATTACH command to insert TIFF as a raster image, then use the image as reference. It’s possible to trace the image.

Is It Possible To Convert PDF To CAD File?

Yes, it’s possible to convert PDF to CAD file. All you need is a PDF to CAD conversion solution. There are a number of available PDF to CAD converters, including Investintech’s Able2Extract, which converts PDF to DWG and DXF formats. Able2Extract PDF Converter is a desktop software, which is free to try for 7 days. There are also some free online PDF to AutoCAD converters, like this one.

Able2Extract Autocad Conversion

If the PDF file was generated from a CAD application, such as AutoCAD, the vector data should be embedded in it, which allows for an easy and accurate conversion.

Do Software Packages That Convert PDF To CAD Files Really Work?

In short: yes, they work. According to a BIM expert and educator, Stefan Boeykens, there are a number of things to keep in mind when converting and evaluating results of a PDF to CAD conversion. Firstly, note that a PDF file is a visual representation of a CAD drawing.  It contains lines, color and text. Thus, when it comes to the conversion output of such files, know that:

  • Lines are, by rule, converted accurately, with an exception to line weights which convert with less accuracy.  
  • Hatches are turned into blocks or groups of lines.
  • With text and dimensions,  the conversion output largely depends on the source. Thus, text can be turned into curves resembling the text, and dimensions become grouped text and lines. There can’t be dimension entity in the conversion output simply because there is no such thing in the PDF.

Note that when converting PDF to CAD drawings, your resulting content will end up as a graphical output containing line-properties, colors, curves, etc.

What Is The Best Format To Transfer CAD Files To Non-CAD Recipients?

The default and usually the best format for non-CAD recipients is the PDF (Portable Document format) as anyone can open and view PDFs on any device. PDFs are non-editable and an obvious choice when the owner or sender doesn’t want the recipient to edit the document.

An alternative to PDF would be DWF as another non-editable file format. However, to open it, the recipient needs to have DWF viewer installed. Compared to the widely used PDF format and the number of freely available PDF readers, chances are that most non-CAD users won’t have the necessary DWF viewers installed on their devices. They may even be unaware of such software, or even if they are, finding and installing would take up extra time.

If you want to transfer the editable CAD file to a client, project manager, tradesman, contractor or any other project stakeholder, the best formats are .DWG or .DXF. If they don’t generally use desktop AutoCAD, they can open the DWG or the DXF files in AutoCAD 360 even with a free plan and make edits to it.

Personalized AutoCAD Workflows vs. Industry Trends

Industrial Technical Drawing

Believe it or not, as advanced and cutting edge as CAD industry workflows seem to be, they evolve and change slowly, if ever. And one thing that certainly never changes for CAD designers is time.

It becomes an even more precious commodity when it’s intertwined with a company’s productivity and deadlines are a priority. As you can imagine, to change up CAD workflows and systems costs not only time, but money and resources, as well.

One such work trend in the CAD industry, for instance, is cloud based technology. Though cloud based tech is heavily advocated in other industries, cloud based CAD is a highly debated topic in the CAD niche. CAD professionals, in fact, are generally resistant to it.

The Resistance To Cloud-Based CAD Workflow Trends

The resistance to cloud-based CAD technology is growing. Robert Green, Cadalyst.com columnist and CAD consultant, sums up the issue of the resistance to Cloud-Based CAD that covers the growing trend in the industry.

In sum, there are key business trends that are keeping companies  from implementing them. This skepticism is for a few reasons, the overarching theme of them being data centralization on the cloud.

Online CAD tools and software flavours have only been coming out over the past few years. And, as with any industry, full adoption of it relies on many existing factors including: cost, software ownership, network security, and prioritizing risk reduction over cost reduction.

Other notable factors include the fact that the cloud is a slow internet-based platform, which will primarily affect the commonly bloated file transmissions the CAD industry is known for. And quite obviously, using such a platform puts users who don’t have the best connection or hardware at a disadvantage.

Naturally, the topic of Green’s article incited a number of comments and reactions from CAD readers. One significant point readers highlighted is that CAD users “don’t appreciate having their software choices dictated to them. The level of disdain for software companies forcing a cloud-based software model onto their customers is palpable.”

It’s also understandable.  How one designer works will always play a major role in deciding what new, more advanced workflows and software can be implemented. Not the other way around.

Freedom To Choose A PDF to DWG Converter

Flight Homes’ timber designer, Paul Erickson, is a real world example of this freedom of software choice in action. And in his case, his choice of software gave him the weekly advantage he needed for projects each week, something that wouldn’t have been possible if the software was chosen for him.

Flight Timber Products Ltd. is a leading construction company in the United Kingdom.  The Flight Timber team struggled with re-entering their PDF drawings manually into AutoCAD, the main productivity and time killer.

Flight Timber Designer

“As successful engineering service providers, the Flight Timber team regularly deals with a variety of PDF files,” says Paul Erickson, designer for Flight Timber Products. “Every employee in the company has their own document management workflow and preferred software.”

And as a CAD designer himself, he tested out a number of converters which never generated the results he needed. He finally discovered and chose Able2Extract as his preferred PDF converter.

Personalizing The CAD Workflow With Able2Extract

In this case study, we take a close look at exactly what the effect of choosing one’s own tools has on a personalized CAD workflow.  Paul Erickson cites benefits from using Able2Extract, which include:

  • 6 hours of time saved per week.
  • Quick and accurate conversions.
  • Interaction with knowledgeable customer service.
  • Easier PDF management.
  • Added bonus of converting PDF to Word for files issued for production.

AutoCAD Tip: Recover Vector Graphics and Text Locked in PDF

As a professional AutoCAD designer, you can deal with any number of CAD drawings on a daily basis that need your attention.  Yet the review process might not always be in an easy, straightforward manner.

The work process is always a collaborative one, and chances are that the people you deal with do not have AutoCAD but some other CAD application that is not able to read AutoCAD’s native DWG format.

To help bridge that gap, professional drafters and designers have, for the most part, resorted to a secondary, more reliable alternative:  the PDF format. You and your clients or colleagues may both be transmitting CAD drawings via PDF to collaborate back and forth on them.

AutoCAD PDF in Able2Extract

Whether these CAD drawings are complex floor plans newly converted to PDF or older archived product designs, the format ensures that both of you can see those CAD drawings as intended, uncompromised.

Yet further on in the workflow, these CAD designs will need modifications, corrections or adjustments before any design plan is finalized.  However, the PDF is a locked down format that makes those vector graphics and text uneditable. You would have to convert the PDF file to a format in order to make any improvements or edits on it.

Able2Extract: PDF to AutoCAD Converter

Our Able2Extract PDF converter is a tool which can accomplish that. As a PDF utility, it is a swiss army knife of PDF converters. It can convert PDF data into more than 10 different formats—AutoCAD included. With it, you can recover vector graphics and text that are locked in PDF.

Though dealing with CAD files may be complex, the conversion method is simplified down to 4 steps:

1. Open the PDF in Able2Extract

Open File Command

2. Select the graphics and text you need to convert with the All or Area selection commands

Selecting content

3. Click on the AutoCAD icon on the command toolbar.

Converting PDF to AutoCAD

Able2Extract will then let you customize your output.  When you select the PDF to AutoCAD conversion command, you are presented with these CAD specific settings:

Able2Extract AutoCAD Conversion Options

You can select DWG (or DXF, if needed) as your conversion output, adjust the color palette, unit measurements, polyline width, and insertion point.  You will also be able to keep those same conversion settings as a default if needed.

4. Click on Convert and save your file to your computer.

Once the conversion is done, you can make any required edits to the recovered vector graphics and text in AutoCAD, continuing on with the review and drafting process.  As an intermediary software program, Able2Extract extracts your CAD content into layers you can easily work with.

Able2Extract PDF Converter is compatible with Windows, Mac and Linux (Ubuntu and Fedora) platforms. You can test Able2Extract’s PDF to AutoCAD conversion feature with the 7-day free trial.

4 Cool Ways To View 3D Content In Your Browser

4 Cool Ways To View 3D Content In Your Browser

From reviewing to editing, projects with 3D CAD models require a lot of collaboration. Whether you’re dealing with engineering designs, architectural layouts, or manufacturing plans, you’ll need advanced applications, like AutoCAD, to generate and fully interact with 3D content.

Moreover, like PDF documents, files with advanced 3D content need special viewers.  However, most CAD applications offer built-in viewers directly within their software. So what if you or your clients don’t have immediate access to the necessary software?

That’s where these resources fit in.  These browser apps allow you to view and share 3D files without the original design software, making a bit of the CAD process easily accessible from anywhere and to anyone with an Internet connection and a browser.

Although these viewers don’t contain the heavy hitting features of full version CAD tools, each one of these has a couple of unique features for practical 3D image viewing online.

* Note that you’ll need a WebGL (Web Graphics Library) enabled browser, one that supports the JavaScript API that renders 3D graphics without a plug-in. These include Chrome 9.0+ , Firefox 4.0+ , Opera 11, and Safari 5.1+ (disabled by default).  (For more details, read Which Web browsers Can Run 3D CAD? by Ralph Grabowski).
